I am confused - KNOX

[tawilker1911]

This is under ALL APPS in my settings but right beside it says NOT INSTALLED... But I can't Uninstall it or Force it to Stop.... Is Knox known for being like a hidden app or... I didn't even install thus app and I have 4 KNOX Apps all of which I can't do anything with but they have access to my entire SAMSUNG GALAXY S4.... These apps are not under DOWNLOADED.... Just under ALL APPS....

Knox is Samsung Security Software that they have been installing on their devices since the S3.

And being under "all apps" but not "downloaded" means that the app came as part of the system.
